My issue with this question is this--
the author never makes any indication that although solar electrical systems didnt work in Brazil, they can be implmented profitably in many countries--my main cause for eliminating it was the fact that it was so strong--that they CAN be implemented in MANY countries? I felt it was way too strong a claim to make without any sufficient support.
I chose C because at the beginning of paragraph 2 it says "the lack of necessary infrastructure has limited effort to provide it" Now, I understand that infrastructure is not synonomous with being densely populated--BUT a densely populated area would have more residents that would be able to participate in implementing the process (which the last sentence indicates is key--local involvement at all levels) and so it would seem that the author would support this idea. It's not perfect, but A just seemed like a choice that would be wrong b/c of lack of support and b/c it's too strong a claim.
It's so frustrating that methods about eliminating incorrect answers that I pick up on other PT's don't seem to apply. Usually if something is too strong a statement to be supported, it is not the correct answer. AH! Had to vent that
